COLUMBIA, S.C. (AP) — A South Carolina man who is scheduled to die next week by firing squad is again asking that his execution be postponed and prison officials release more information about the state’s lethal injection drug and procedures.

Brad Sigmon, set for execution by firing squad on March 7, seeks a delay, citing concerns over South Carolina’s lethal injection process. If carried out, it would be the first U.S. firing squad execution since 2010.

Condemned South Carolina inmate Brad Sigmon has chosen to die next month by a firing squad, a method of execution that has not been used in the U.S. in 15 years.

Brad Sigmon was convicted of beating two people to death with a baseball bat, and he’s scheduled to be executed in weeks. But instead of lethal injection, Sigmon chose to be executed by firing squad.

The state has never used that method to execute a prisoner. The last time an inmate was killed by a firing squad was in 2010 in Utah.

Brad Sigmon chose bullets over lethal injection or the electric chair, "which would burn and cook him alive," his attorney said.

Brad Sigmon made the choice after the state Supreme Court denied a stay request based on questions about the effectiveness of lethal injection

Arizona has 112 death row inmates. Firing squad as a means of execution has been in the headlines more and more. On Friday, a South Carolina man chose death by firing squad for his planned execution in two weeks.
